The aim of this study was to analyze the work and life balance of unmarried working cases in single-person households. Eleven cases were interviewed with a semi-structured questionnaire. The results were as follows: When they were starting as a single-person household on their own initiative and with enough preparation and planning, they expressed higher satisfaction as a single person household. For their adaptation to being a single-person household, practice education and information about household work and self-care were useful. Their thought about 'life' are focusing on self improvement and leisure activities either alone or with their friends. Their family interactions were performed with financial, emotional, and housework support from each other. Resources such as money and time were the major factors that impacted work and life balance. For work and life balance of single person househods, the cases needed political support for financial aid and flexible work arrangements.

Objective : The purpose of this study was to examine the validity and reliability of the Korean version of Life Balance Inventory (K-LBI) and to present the relationship between life balance and sensory processing. Methods : K-LBI was constructed through forward and backward translation. Convergent validity, internal consistency, and test-retest reliability were tested for college students. To verify convergent validity, correlation analyses between K-LBI and Korean version of Perceived Stress Scale, Korean version of Satisfaction With Life Scale, and Adult Self Report-Achenbach system of empirically based assessment were performed. Split-half reliability and test-retest reliability were also obtained for reliability verification. We performed the correlation analysis between K-LBI and Korean version of Adolescent/Adult Sensory Profile. Results : A significant correlation was found between K-LBI and the scales for convergent validity. A favorable split-half reliability and test-retest reliability were calculated. The positive correlations were found between relationship life balance and sensory sensitivity/sensation avoiding quadrants. The negative correlation was found between challenges life balance and low registration. Conclusion : This study shows that K-LBI is a valid and reliable tool in Korea. It also provides an in-depth understanding of the relationship between life balance and sensory processing.

This study examines the distribution of power in Northeast Asia based on the balance of power theory, a representative theory of realism, assuming military capabilities as the core power of states. The results of previous studies on the balance of power and military forces are reviewed and used to analyze changes in the strength of the US, China, Russia, Japan, South Korea, and North Korea through 2020 to predict the security environment in 2030. In the balance of power theory, if the balance of power between a nation or a group of powers collapses, the possibility of war is high, and to survive in the international community with high uncertainty and distrust, the theory predicts that states must increase their powers in a self-help world and strengthen cooperation and alliance. Countries in Northeast Asia are also continuing to strengthen their military capabilities, and countries neighboring China are paying keen attention and remaining vigilant due to the rapid changes in the international security environment after the rapid rise of China. To mark the future 100th anniversary of the Chinese armed forces in the 2030s, China aims to realize 'defense and military modernization' and build a 'world-class military force' by the nation's 100th anniversary in the 2050s. The US is busy checking China's rise by strengthening international cooperation and alliances. The security environment and power dynamics in Northeast Asia are slowly changing as the US and China continue to compete for global hegemony. The changes and implications of the distribution of power in Northeast Asia after 2030 are examined based on the balance of power theory.

The elderly people with advancing years have many problems such as the decline of the proprioceptive, visual & vestibular function and muscle weakness. Furthermore the decrease of the reflex which influences the balance ability in sudden change of the movement could cause the falls. The difficulty of the balance caused by the fear releated to the fall aggravates the Falls Efficacy and causes a lot of the disability of the independent activities of daily living. The purpose of this study was the effect of a Virtual Reality Program on Static Balance control and Fall efficacy of Elderly people. 14 elderly people(subjects) who were ≥65years of age partiripated in this study and they were divided into VR(Virtual Reality) group(n=7) and Control group (n=7). VR group took the general physical therapy & IREX and only the general physical therapy was carried out in the control group. VR group of intervention was carried out for 30min. total 8times. They were evaluated by BIO-Rescue, Fall Efficacy Scale before and after treatment. The Static Balance control and Fall efficacy were assessed by Bio-Rescue & Falls Efficacy Scale. The analysis of the resulf was assessed by Wilcoxon signed test & Mann-Whitney U test. The result showed that the static balance of VR group with the open eyes was improved in a static balance test and range of the movement was increased in limited of stability. And Falls Efficacy was also efficacious. IREX was effective to static balance control and Falls Efficacy of the elderly When we think about these effects, various treatments and objective assessments using VR program will be needed for the elderly

본 연구는 Usability의 투자 성과관리(ROI: Return On Investment)를 위한 균형성과지표(BSC: Balanced ScoreCard) 관점에서의 Framework 개발을 목표로 한다. 2000년 이후 Usability에 대한 투자 규모는 높은 증가세를 유지해 왔으나 대규모 투자가 진전되는 가운데 Usability투자의 수익성을 어떻게 확보하고, 그 효과(Effectiveness)는 어떻게 측정할 것인가 하는 문제는 상대적으로 관심을 끌지 못하고 있다. Usability 투자에 대한 시스템적 성과관리를 위해 개발된 Usability BSC Framework은 BSC의 4가지 관점에서 Usability 투자성과관리에 대한 변형된 관점의 모델을 제안한다.

본 논문에서는 기존의 정적인 스케쥴링 모델 즉, 그래프 이론, 정수 프로그래밍 그리고 휴리스틱 모델에 근거한 알고리즘들의 사례를 소개하고 분석하였으며 정적인 스케쥴링 알고리즘의 단점을 보완할 수 있고 고장허용구조를 지원할 수 있는 FAME 알고리즘을 제시하였다. FAME은 정적인 휴리스틱 알고리즘과 동적인 스케쥴링 알고리즘으로 구성되며 부하균형과 기억공간 크기 그리고 최소 통신비용 조건을 만족하고 태스크간 간섭비용을 도입함으로써 태스크간 통신 비용에 의해 나타날 수 있는 태스크들의 동시성 수행 정도의 감소를 방지할 수 있도록 하였다. 또한 기억공간 크기와 간섭비용의 조합은 테스크들이 일부 프로세서에만 할당되는 현상을 방지할 수 있다.

83년 7월부터 NYMEX 선물시장에서 거래되기 시작한 원유선물은 90년대 들어 주식 채권 외환 등의 금융시장과 관련하여 크게 성장하고 있으며, 원유선물가격이 현물시장에서의 가격형성에 큰 영향을 미치고 있다. 따라서, 원유선물가격이 미래의 현물가격에 대한 최적의 예측치라고 하는 합리적기대모형(合理的期待模型)에 의거하여 원유선물 가격과 현물가격의 변화추이 및 그들 사이의 장(長) 단기(短期) 균형관계(均衡關係)(동태적통합(動態的統合))와 효율성(效率性)등을 일별(日別) NYMEX 선물유가(근월도래선물(近月到來先物)의 종가(終價))와 WTI 현물유가의 자료를 이용하여 계량분석하였다. 원유선물가격과 현물가격은 단위근(單位根)을 갖는 불안정(不安定)한 시계열이지만, 선물유가와 현물유가사이에는 공적분관계(共積分關係)(공통확률적추세(共通確率的趨勢))가 있어 장기적(長期的) 균형관계(均衡關係)가 존재하며, 또한 공시계열상관관계(共時系列相關關係)(공통안정적순환(共通安定的循環))가 있어 단기적(短期的) 균형관계(均衡關係)도 존재하는 것으로 보여진다. 그리고 선물유가는 미래의 현물유가에 대한 예측력이 있는 것으로 보여진다. 따라서, 원유선물가격이 미래의 현물가격에 대한 최적의 예측치라고 히는 합리적기대모형(合理的期待模型)과 일치하는 것으로 나타났다. 원유선물가격이 현물가격과 장(長) 단기적(短期的)으로 동태적(動態的)인 균형관계를 보이고 있으므로 정부의 합리적인 수입선다변화정책과 유가자유화에 따른 석유업계의 효율적인 운영방안의 하나로 원유선물시장의 활용이 더욱 더 필요할 것으로 생각된다.

The Purpose of the study is to analyze the change of the unbalanced national development by the construction of multifunctional administrative city and innovation cities. In this study, index of unbalanced national development is measured by unbalanced distribution of population on national land. Gini's coefficient is used to measure the unbalanced distribution of population. As a result, the construction of multifunctional administrative city and innovation cities will relieve the unbalanced national development. but the effect will be insignificant. For the relief of unbalanced national development, various policy and strategy will have to develop.
